Overview The SV9520 SmartValve� System Controls combine gas flow control and electronic direct main burner ignition sequencing functions into a single unit and provide all gas ignition safety functions by controlling gas flow ignition source and air blower. Features The control communicates directly with the ST9160 Electronic Fan Timer (EFT) in typical forced warm air furnace applications. It will interface with the 208907 Terminal Board providing compatibility with power-stealing thermostats.It can directly interface with the appropriate power supplies and a system thermostat for additional appliance applications. When controlled directly by a thermostat the control does not provide a postpurge function as power to the control is removed when the thermostat call for heat ends. This system is suitable for a wide range of fan-assisted combustion gas-fired appliances including furnaces rooftop furnaces boilers unit heaters infrared heaters water heaters and commercial cooking appliances.
